Gestational Treatment With Ursodeoxycholic Acid Compared to Placebo to Reduce Severity of Gestational Diabetes Mellitus

IMIB-GU-2019-02

The trial will compare the influence of treatment with ursodeoxycholic acid (UDCA) compared to placebo on glycaemic control (primary outcome) in women with GDM after a positive diagnosis at 24-28 weeks of gestation. The investigators will evaluate maternal and fetal lipid and glucose metabolism. Neonatal health outcomes will also be studied, including the rate of LGA. UDCA is used to treat the commonest liver disease of pregnancy, intrahepatic cholestasis of pregnancy (ICP), and has good safety data to support its use in pregnancy 52-57 ., it means, no studies reported any increase in adverse outcomes associated with UDCA treatment. It is noteworthy that in the largest study 52, 8 serious adverse events were reported, 6 of which were in the placebo group, and none were considered to be related to the trial intervention. There were 72 adverse events: 31 in the ursodeoxycholic acid group and 41 in the placebo group. The same number of patients in each group (n=10) reported adverse events related to gastrointestinal disorders.
